I've never developed skill in night photography, but I soon want to begin to try it. You've got some great shots there.Please come link up at http://image-in-ing.blogspot.com/2015/09/allium-glorious.html

The buildings with lights on them at night are very festive. It looks like a big city out of your hotel window, hard to tell it is Australia. I'm trying to imagine what the stage for the Opera House looks like for performances.

Your night photos were beautifully taken even without tripod. I wonder which model and brand of camera you used? I never used tripod and I should consider using one. I am still dreaming of the day I could visit Sydney.

Please examine Sydney Harbour Bridge precisly again - two light weight mobile robot arms from SCHUNK (the company I work for) are doing maintenance work (sand blasting) at this bridge to preserve it from rust! http://www.es.schunk.com/schunk/schunk_websites/news/subject_of_the_month.html?article_id=23554&country=ESP&lngCode=ES&lngCode2=ES I like all of your night shots and would have been glad to take my own ones there!Enjoy your weekend,
